A peek at the Model 3. Hints for ordering solar roofs. The CEO’s travel plans.

It’s not only President Donald Trump stirring up followers on Twitter. Tesla CEO Elon Musk Friday took to social media for his occasional series of product promotion, fan Q&A and company cheerleading.

Musk posted a six-second video of a production-ready Model 3 driving along a dark street. The company plans to begin wide production of the car in July and deliver it to consumers this year. The first models are expected to go to Tesla employees.

The Model 3, pegged for a base price of $35,000, will be a smaller and more stripped-down version of the Model S. Musk said the Model S will remain the company’s fastest car, until a new version of the roadster arrives in a few years.

Musk acknowledged another vehicle in the planning stages — the Model Y — completing the Tesla “S-3-X-Y” collection of electric vehicles. The CEO shared the origin of the new sedan’s name: “Model 3 was going to be called Model E, for obvious dumb humor reasons, but Ford sued to block it, so now it is S3X. Totally different :)”

Musk added that the company would begin taking orders for solar roofs in April. Tesla has not released the price for a solar roof, which is expected to be made at the SolarCity factory in Buffalo, N.Y.
